After 5 games you can make that assertion? New players, new starters, new system and you expect it to come together so fast?

Can we at least give this team time to gel and learn their roles and adjust to playing together? Mcguire and Ed as starters?

Assertion?! Have you been watching the games?
Even if our "new" (what's the real problem?) guys were better defenders, but played worse than the second unit due to chemistry issues, it'd still be wise to use our gelled unit to put the stamp on the game first.
As things stand now not doing so guarantees failure.
